[PATCH] IBM Z: Avoid bash-specific substitution in configure

[PATCH] IBM Z: Avoid bash-specific substitution in configure

[Marius Hillenbrand]

Tested configure runs on NetBSD x86-64, Linux on x86-64 (with target s390x), and
on s390x.

Is the patch ok for master, and for gcc-11?

----8<------8<------8<-----

Fix a bootstrap error observed on NetBSD.

	PR bootstrap/100552
